Selling One of wo properties that share same address & utilities

[Cham Vee]

It's zoned as multi-family.  This property has two units on the same lot. The primary unit is 1650 sq ft and the secondary unit is 1350 sq ft. Both units are separated by a fence but share the same address and utilities.

My question is can I separate addresses and utilities and sell the second unit (1350 sq ft) as a Single family home?  TIA
